Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Does Watershed Make A Difference?

Jeff Ostrowski · September 13, 2017

4450 picture S YOU KNOW, all of us here at Watershed are volunteers. We have no staff and no salaries. Every so often, my fellow bloggers and I wonder if we are making an impact on the “real world.”

Here’s something powerful we recently received from Maryland:

Dear Corpus Christi Watershed,

I wanted to send a note to tell you what an incredible blessing your webpage and blog have been to me.

I am a vocalist and have been all my life. I am very studied, though I have no formal degree in music (in high school, thinking I’d never pay the bills with music, I got a degree in something else that makes no money and required a Master’s degree for employment!). I am an educator by trade. When I had my first child, I quit working full time but was asked shortly after to cantor at my parish—I wasn’t even fully Catholic at the time! Through much prayer, I discerned God was calling me to lead my parish’s music program when our brand new pastor came to our parish in 2013. I was hired as a part-time music director in early 2014 (right before finishing RCIA and being received into the Church at Easter Vigil).

For the past 3.5 years, I have been systematically implementing much of the good advice and practice I’ve gleaned from reading Views from the Choir Loft and endlessly exploring the Watershed website. Formerly our parish had folk Masses, Breaking Bread Missals, a volunteer choir that didn’t formally practice, and cantors only at big events. Now we have mostly organ-led Masses every weekend and feast, a more traditional Missal and Hymnal—allowing us to implement the communion antiphon—a regularly meeting and practicing choir, and (last year) we regularly sang in 2-part harmonies!

This past spring, you re-posted the Polyphonic rehearsal videos on Facebook and I knew I had to take advantage of that golden resource. Our county’s deanery planned a Fatima pilgrimage: a celebration the 13th of the month for six straight months at a different parish around the county. I knew when I saw those rehearsal videos that we had to utilize them for our turn (which was tonight).

I have an all-female choir of about 8 dedicated women who sing every Sunday. During Christmas and Easter I convene a “festival choir” and get a few more volunteers to make our bigger Masses more special. So, I recruited another 15 men and women to join us for tonight’s Mass, using music almost entirely from your page:

—Guerrero’s Missa Iste Sanctus

—Hymn to Mary

—Hail, Holy Queen

—A communion antiphon for the Marian Mass we chose that Richard Rice whipped up for me when I cried for help on the CMAA page a few days ago!

—Filled out the time with a few well known Marian and Eucharistic hymns.

We had about 250-300 in attendance (full for our little parish). It was a huge success! My pastor was blown away at the beauty of the Mass setting by Guerrero. The people in attendance were just floored by how the 4-part choir enhanced the Mass. To quote our priest and echoed by others, they felt “like we were in heaven.” One older gentleman and his wife approached me after Mass and thanked me for the pleasant surprise. He said “I already knew I was going to witness the miracle of the Blessed Sacrament tonight, but never did I think I’d open a program and see the MISSA ISTE SANCTUS.”

I just cannot thank you enough for how much your ministry has helped me grow and helped me introduce my parish to the incredible sounds that the human voice is capable of. I hope you’ll share some of my story on your blog and social media to encourage others to get out of their comfort zone and try beautiful things in their liturgies! My only regret is that with the stress of the night, I didn’t get any video or audio to send to Jeff Ostrowski so he could he could hear how all his soprano singing was worth it—to see little old ladies and scared young tenors singing sacred polyphony for the first time in their lives!


For whatever reason, these last two weeks have been full of heavy crosses.

A letter like this was so gratifying to receive!

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must simultaneously serve as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors composed this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria,” a piece which is frequently requested for Catholic funerals and weddings. In terms of the discussion about whether that piece is too theatrical (‘operatic’) for use in Church, I will leave that discussion to others. All I know is, many church musicians out there will appreciate this simplified version.

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“Many other things most justly keep me in the bosom [of the Catholic Church]. The consent of peoples and nations keeps me in the Church; so does her authority, inaugurated by miracles, nourished by hope, enlarged by love, established by age. The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep, down to the present episcopate.”

— Saint Augustine (Epistle against Manichaeus)
